MEANS FOR AND METHOD OEv ATTACHING SHOOTING STRIPS.

Application led September This invention relates to means for and a method of attaching shooting strips to secure square edges at the tops of beams.

In the construction of floors and the like there may be formed a floor proper of reinforced concrete supported on the tops of` against a member at the position where it y is desired to apply the material. It shouldv be understood that before leaving the nozzle, the material inv the mixture` is moistened `sufficiently to cause it to stick to the surface to be coated.

An object of the invention is to provide` novel means for shaping the covering of a support for afloor or the like.

Another object is to provide a novel method for shaping the covering of a support for a iioor or the like.

A further object of the invention is to provide a new method of attaching shooting strips to the lower side of floors or the like.

In carrying out the invention as applied to the covering of an I beam or flanged member on the top of which rests concrete floor, a suitable strip is attached tothe lower surface of the floor by suitable adhesive materia-l and in a position parallel to the edge" of an upper flange of the supporting member. Then, when the material is shot into place, the covering of the flange will have a square edge. The shaping of the edge of the covering` of the opposite upper flange may be effected by using the same or a simi-V lar strip in the same manner.

rPhe adhesive material used may be glue,

Aplaster of Paris, gypsum or any suitable quick setting or positively7 adhering material. Other objects and advantages will appear upon consideration of the following ldetailed description and the drawings in which:

application of a shooting strip at one side of the supporting member or beam;

Fig. 2 is a side view showing a shooting strip attached to the lower surface ofthe floor; and l Fig. 3 is a cross section view illustrating the use of a tack or nail in'holding the adstrip.

In Figure l there is shown an-I-beam lf on the` upper edge' of which rests a floor 2 which may be of poured concrete. tice it is found desirable to cover such beams as l with coverings of cementitious material,

preferably shot intovpla'ce. A mixture of cement and sand in proper proportions is placed in a device from which it is forced I through a nozzle under suitable pneumatic pressure and driven or shot into place. Before placing fioin the nozzle of said device the material is sprayed with water to a sutilcieiit extent to make it adhere to the surface T against which it is blown. In forming such coverings 3 as shown in Figure l, diiiiculty is found in giving the -proper shape to the material covering the 'upper flanges -fl and ythe lower flanges 5, and particularly the upper fianges, due tothe inconvenience of holding-suitable shooting strips inposition. It is also of great importance to have the shooting strips as simple in form as possible and to have them fastened in position by as simple a means as possible.

According to the present invention use is made of an ordinary strip 6 secured in position by material secured theretoV and adhering to the lower surface of the floor 2. For attaching the strip in this way, use may be made of-any suitable material such as glue,

Vplaster of Paris, and gypsum. To give satisfactory results the attaching material must be quickly set and must adhere strongly.

As shown more clearly in Figure 2, the attachingmaterial may be applied in portions 7 at spaced intervals along strip 6 and such portions of attaching material 7 may be heldl more strongly in position on the strip 6 by suitable fastening devices such as nails or tacks 8 having their heads projecting In pracslightly above the upper surface of the strip i so as to be engaged strongly by the attaching material and held in position on the strip 6.

It will be seen that the tacks or nails 8 serve also to space the strip 6 from the lower surface of the floor 'and that by spacing the los portions of connecting material 7 that spaces are left between tliestrip and the lower surface. of the floor so that the strips canbe more easily removed after the covering for the upper flange has been completed,

Although the present invention is illustrated only in connection with the support otl the shootingstrip against the lower siii'- face of a floor it should be understood that the invention may beapplied in the attachinent of shooting strips in other positions.

lt should be understood that- Various changes may be inade in the shape of the .strip and in the means `for securing the strip in position, and also that variousclianges ina7 be made in the herein disclosed method of securingipi'eper form for the ceinentitious covering 'oit the flanges, without departing frointhe true spirit and scope of the invention.

Having thus described my invention, I claim:

l. Means for shaping ceineiititious inaterial around the flangcsat the upper edge of a beam in contactwith the lower surface of a fioor, comprising a shooting strip adjacent the edge ofone of' the flanges at the upper edge of said beam, and strip supper-ting means attached to said strip and adhering` to the lower surface of the floor.

Q. Means for shaping ceinentitious materia-.l around a flange at the upper edge of a beam in contact with a flat surface of an overhanging member, comprising a strip, and means for supporting said strip in effective position parallel to the edge of one of the fianges at the upper edge of said beam, comprisingn'iaterial attached to said strip atrinterrals tlierealong and adhering to the lower surface of saidoverhanging member.

3. Means for shapingl cementitious material placed around the flanges at the upper edge of a beam-in contact with the lower surface of a floor, comprising a strip adjacent the edge of one of the flanges at the upper edge ot' said beam, and strip supporting `means including material adhering to the lower face of said floor and fastening der` vices extending from said material into said strip. i

i Ll. A nietliodof forming a covering for an upper flange of a flanged beam or the like on which rests a floor or the like, including applying adherent means to the upper surtace of a shooting strip, placing said strip in position adjacent the edge of the flange to be covered, pressing said strip upwardly against said 'floor to cause said material to adhere to the lower surface of said floor, and shooting cenientitious iiiatei'ial into place hetween said shooting sti'ip'and said beam. to cover said flange.

5. A method of forming a cen'ientitious corering' for a fiange at the upper edge of a flanged beam or the like on which a flool rests, coniprisii'ie' attaching a forni te the louter surface or the floor by the use of quick set-ting plastic material and in a position ad jacent the edge of said flange, shooting cenieniitious material into pusition between said strip and said beam and arouinl said flange, and removing said forni.

fi. A. method vof `t'oi'n'iing a ccnientitious covering for one of two engaging members which include; securingl a shooting strip in position on one of' said members by quick setting material placed therebetween, .shoetiiig cenientitious material into pesition and removing the strip.

.7. A method of forming a ceinentitious covering for one of two adjacent members which includes ecuring a form in position on the other of said members by quick setting material placed tlfierebetween, placing cen'ientitious material in the form, and reinmfing the form.

In testimony whereof he afiixes his signature. 'i
